Number the bottles 1-5. Collect a number of pills from each bottle corresponding to their bottle number. So, 1 pill from bottle 1, 2 from bottle 2, etc. If they all had 10 gram pills they should weigh 150 grams. The difference will be the number of the bottle the 9 gram pill came from. Example, bottle 3 has the 9 gram pills. Total weight read will be 147 grams. The difference of 3 is the bottle it came from. Menos

Place all five bottles on the scale. It should say 49 grams on the scale. If you take out one bottle each time. Subtract the scale from before and after the bottle that has been taken off the scale. If it's 9. That's the bottle you're looking at. Menos

I answered perfectly with examples as I am confident and strong on technical.

what was the aptitude qus? is it mathematical related or any other types ?
↳
its very simple. we clear from the question that (number of balls * volume of ball)=volume of the cuboid so, (n * 4/3 *PI*r^3)=a^3 here radius of the ball is 5cm and side of the cuboid is 100cm..Substitute these all values in the above..so ans is 1909 balls can be fitted.. Menos

This may be a trick question, so ask questions to make sure you understand what's being asked of you. Menos

Fill the 5 litre can from the tap Empty the 5 litre can into the 3 litre can - leaving 2 litres in the 5 litre can. Pour away the contents of the 3 litre can. Fill the 3 litre can with the 2 litres from the 5 litre can - leaving 2 litres in the 3 litre can. Fill the 5 litre can from the tap. Fill the remaining 1 litre space in the 3 litre can from the 5 litre can. Leaving 4 litres in the 5 litre can. Menos

Fill both jugs then use a measuring cup because you cannot "eye ball" exactly 4L of water. You need to use a tool this is a trick question that has nothing to do with math. Menos

The process of having to complete a case study that required 4-6hrs of the candidate's personal time before there was an opportunity to have an in person interview is too demanding and not typical of the industry. The case study was requested on short notice, on a Wednesday, with a deadline of Friday 8PM. In my opinion this is unreasonable for individuals already working full time with families. Despite being fully capable, excited, and qualified for the role (arguably over-qualified), I was rejected from the role (post-case-study) because I was too busy to give as much attention to the onerous interview process compared to other candidates.

Print the numbers form starting to end values without printing the numbers with same digits like from 10 to 20 , print 10,12,13.........20 except 11. int start=10; int end=20; for(int i=start;start<=end;start++) { String num=Integer.toString(start); if(num.charAt(0)!=num.charAt(1)) { System.out.println(start); } } Menos
